Mitigating Controls

Likely Mitigating Controls AI

Per-CVE control mapping for this CVE has not run yet; the list below is derived from the weakness types (CWEs) cited in the NVD entry.

addresses: CWE-286

Directly implements correct management of identifiers for individuals, groups, roles, services, and devices.

addresses: CWE-286

Requires confirmation and adjustment of user access rights during personnel transfers, mitigating incorrect user management.

Mitigating Controls (ISO/IEC 27001:2022 Annex A) AI

Derived directly from the weakness types (CWEs) cited in the NVD entry via our AI-authored CWE→ISO cross-walk (authority under review) — links open the control.

blocks

Access control policies rely on accurate user management but do not themselves define user lifecycle processes.

blocks

A.5.16 directly governs identity lifecycle (unique binding, timely disable/remove, no duplicates, oversight of shared/non-human) which stops most incorrect-user-management flaws from being exploitable; bounded remainder exists for flawed access-rights assignment logic after identity is issued (belongs to A.8.3).

blocks

A.5.18 directly governs the full provisioning, review, adjustment and timely revocation lifecycle for access rights (including segregation, authorization, activation only after approval, and pre-termination review), which stops most incorrect-user-management cases from being exploitable; the bounded remainder is flawed user-lifecycle logic inside the product itself that the organizational process cannot reach.

blocks

A.6.5 defines post-termination responsibilities, confidentiality duties, role handovers and communication processes; it has no bearing on whether a product correctly manages users in its environment, so the weakness can still be present and exploitable.

blocks

A.8.2 directly controls allocation, review, expiry, temporary use, separate identities and higher authentication for privileged rights per 5.15 policy, which stops most incorrect-user-management cases (e.g. over-provisioned or stale privileges) from being exploitable; the bounded remainder is incorrect management that is not privilege-related at all (e.g. ordinary user creation, password resets, or account lockout logic).

Hardening callouts derived

DISA STIG baselines are authored against specific weaknesses. Where this CVE cites a broad weakness class, the mapping is not asserted at that abstraction (owner ruling, 2026-09-25: grade only at Base and below), so no rule is shown here rather than a rule shown against the wrong grain.

  • No fine-grained STIG row for CWE-286, a class-level weakness. Rules are authored against its narrower children: CWE-842.
